Photosynthetic suspended-growth systems in aquaculture
TLDR
The principle advantages of photosynthetic suspended-growth systems are lower capital costs relative to other recirculating aquaculture systems and increased control over stock management relative to conventional static ponds and the main disadvantage is the relatively low degree of control over water quality and phytoplankton density, metabolism, and community composition.About:

Nitrogen removal techniques in aquaculture for a sustainable production
TL;DR: The periphyton treatment technique is applicable to extensive systems, and the proteinaceous bio-flocs technology can be used in extensive as well as in intensive systems, which provide an inexpensive feed source and a higher efficiency of nutrient conversion of feed.

Biofloc technology in aquaculture: Beneficial effects and future challenges
TL;DR: In this review,Biofloc technology is a technique of enhancing water quality in aquaculture through balancing carbon and nitrogen in the system, with the added value of producing proteinaceous feed in situ.

The biofloc technology (BFT) in indoor tanks: Water quality, biofloc composition, and growth and welfare of Nile tilapia (Oreochromis niloticus)
M.E. Azim,David C. Little +1 more
TL;DR: Overall fish growth and production was poor in terms of commercial feasibility and a modified system design that would allow enhanced feed and biofloc utilization is proposed.

Aquaculture environment interactions: Past, present and likely future trends
TL;DR: There does not appear to be a panacea for environmentally sustainable aquaculture on the horizon to meet the increasing demand for aquatic food, but improving existing technology is more likely to be met through improvements in existing technology.
Journal ArticleDOI
Suspended solids removal to improve shrimp (Litopenaeus vannamei) production and an evaluation of a plant-based feed in minimal-exchange, superintensive culture systems
TL;DR: It is shown that controlling the concentration of particles in superintensive shrimp culture systems can significantly improve water quality and shrimp production and an environmentally friendly and potentially economical plant-based diet can produce results comparable to a fish-based feed in super intensive shrimpculture systems.

Microbial changes occurring at the sediment-water interface in an intensively stocked and fed fish pond
TL;DR: Upon establishment of anaerobic conditions a large microbiological community is present capable of mediating the chemical reduction of SO 4 2− to H 2 S, or other transformations resulting in products which contribute to fish growth inhibition commonly observed in such intensively stocked and fed fish ponds.

Influence of dissolved oxygen on the nitrification kinetics in a circulating bed biofilm reactor
TL;DR: In this article, the influence of dissolved oxygen concentration on the nitrification kinetics was studied in the circulating bed reactor (CBR), and the results showed that either the ammonia or the oxygen concentration could be limiting for the nit- rification kinetics.

A simulation model of ammonia dynamics in commerical catfish ponds in the southeastern United States
TL;DR: In this paper, a mechanistic model was developed to simulate annual variation of ammonia concentration in commercial (levee-type) catfish ponds in the southeastern United States, where two primary source processes (fish excretion and sediment diffusion) and two primary sink processes (phytoplankton uptake and nitrification) were considered.
Journal ArticleDOI
CFD modelling pond dynamic processes
TL;DR: Ponds and aerators can now be objectively coordinated to achieve more productive culturing conditions and portions of pond bottoms found to experience high shear stress are identified for reinforcement to prevent the sedimentation of sludge in otherwise productive zones.

19 Partitioned aquaculture systems
TL;DR: Low capital cost and the relative reliability offish production are the major advantages offish culture in earthen ponds, but the need for continuous management of dissolved oxygen concentrations, as well as other fluctuating water quality variables, represent additional management difficulties.
